MALT-DRIER.

SPECIFICATION forming part of Letters Patent No. 554,509, dated February11, 1896. Application filed September 14, 1895. Serial No. 562,484. (Nomodel.)

To all whom it may concern.-

Be it known that I, LOUIS A. HENZE, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Malt-Drying Processes; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to malt-driers, and has for its object animprovement in buildings in which malted barley or other malted grainmay be dried rapidly and perfectly without the usual labor of handlingand otherwise treating the same.

In the drawings, Figure 1 is a cross-section of the building andappliances contained therein. Fig. 2 is a sectional longitudinal view ofthe main shaft of the drier.

A indicates the walls of the building, which is in the form of an ordinary' rectangular building provided with a gabled or hip roof, with asuitable chimney-orifice. Centrally through this building extends ashaft B, terminating at its ends with bearings 17 b, which are held insuitable boxes supported in the main walls of the building, or in anyother suitable way. The shaft B supports a number of rectangular boxes,the upper and under walls of which are made of perforated materialhaving perforations so coarse that heated air would pass through them,but so fine that the malted grain would not pass through. This may be ofperforated sheet metal, or woven material, or any similar suitablesubstance. The ends of the several boxes are supported and held inposition bya ring (Z, and there may be of these rings (each of which isconcentric to the main shaft B) any suitable number to furnish propersupport to the boxes 0 c. The ends of the boxes, by which is meant thoseportions which are parallel with the main shaft B and join theperforated upper and under sides, are made in the form of doors e e,hinged to the under piece so that they may be readily opened, asindicated in Fig. 1 at e and c and they are also provided with properhasps and catches to hold them shut at times when it is not desired tohave them open. Through one of the side walls of the building there is,near the top, a chute S, and an inspection-door or a number ofinspection-doors t, and on the same side of the building, nearthe bottomof the wall, there is an exit-chute R and an inspection-door 1'. Thedoor 6 when open, as shown in Fig. 1, forms a prolongation at the bottomof the chute S, and guides grain thrown into the chute S directly intothe box 0. The door 6, when in the position indicated in dotted lines inFig. 1, forms a continuation of the bottom of the box 0, and directs theoutflowing grain from box 0 into the delivery-chute R.

f f indicate two driving-rollers suitably mounted on frameworkin thebuilding, and one of which at least receives motion from some externalsource, as the driving-wheel F. (Shown in Fig. 2.) Motion communicatedto these driying-wheels, acting by friction on the rim (Z, serves torotate the drying-boxes c c on or with the shaft B, so that both sidesof the boxes 0 c are successively brought and repeatedly brought, ifdesired, next to the top of the furnace G.

H H indicate side guards secured to the walls of the building andextending for about ninety degrees into close contiguity with the pathsof the ends of the drying-boxes c c, the purpose of these guards beingto prevent the rising heat from passing between the ends of the boxesand the walls and compelling it to pass through the contained material.The doors a" and t furnish a ready access to the interior of thebuilding at a place such that the contents of the boxes may be inspectedat any time, and the flap-doors c 6 may be opened or closed as desired.

The boxes 0 a may be opened from one end to the other, giving freepassage-way to the material, or they may be closed by cross-partitionsaround the shaft, as indicated in Fig. 1, it being immaterial to thesuccessful working of the devices whether there be free passage-way tothe material clear across the box or only part way across it.

What I claim is 1. In a dry-house for malt, the combination of a centralshaft, drying-boxes extending radially from the shaft, provided withperforated inclosing walls parallel with the radial line from said shaftand with doors at the ends of said boxes adapted to form eontinuationsof said inelosing walls and a guarding partition adapted to direct theheat through the drying-boxes, substantially as described.

2. In a dry-house for malt, the combination of a central shaft,drying-boxes extending radially from the shaft and provided withperforate inolosing Walls parallel With the radial lines from saidshaft, and with doors at the ends of said boxes adapted to open outwardas extensions of the box sides, an inletspout adapted to deliver intothe open end of a box when near the top, and an outlet-spout adapted toreceive and conduct the outflowing malt from a box when near the bottom.

In testimony whereof I sign this speoifioation in the presence of twowitnesses.
